Abstract
Klefbeck B, Hamrah Nedjad J. Effect of inspiratory muscle training in patients with
multiple sclerosis. Arch Phys Med Rehabil 2003;84:994-9.
Objective:
To evaluate whether inspiratory muscle training (IMT) improves inspiratory muscle
strength, respiratory capacity, fatigue, and subjective perception of physical endurance
in patients with advanced multiple sclerosis (MS).
Design:
Randomized controlled trial.
Setting:
Outpatient clinic in Sweden.
Participants:
Fifteen severely disabled patients with MS, randomized to a training or control group.
Intervention:
Seven patients trained with a Threshold inspiratory muscle trainer, twice every other
day, with 3 sets of 10 loaded inspirations (40%–60% of patients’ maximal inspiratory
pressure [Pimax]) over a 10-week period.
Main Outcome Measures:
Spirometry, Pimax, maximal expiratory pressure (Pemax), clinical assessments, and questionnaires on the patients’ fatigue severity and
physical endurance were evaluated.
Results:
After training, the Pimax (P<.008) and Pemax (P<.02) increased in the training group. The improvement in Pimax after 10 weeks of training was higher than the improvement in the control group
(P<.01) and was maintained 1 month after the training period ended. The training affected
neither respiratory function nor the patients’ symptoms.
Conclusions:
IMT had a beneficial effect on inspiratory muscle strength in patients with MS and
is recommended as a complement to ordinary physical training.
